Answer:
Step-by-step explanation:
6 miles in 49 minutes = x miles in 1 minute
proportion time
6 x
------- = ------ cross multiply
49 1
49x = 6 ......divide both sides by 49
x = 6/49
x = 0.12244 rounds to 0.12 miles per minute <====
===============================
22 bucks for 5 hrs = x bucks for 1 hr...
22 x
------ = -------- cross multiply
5 1
5x = 22...divide both sides by 5
x = 22/5
x = 4.4.....so its $ 4.40 per hr <===
The zeros are -8, -1, 2, so you can write the function as f(x)=(x-(-8))(x-(-1))(x-2)=(x+8)(x+1)(x-2).
Expand:
The function is f(x)=x³+7x²-10x-16.
The missing value is 7.
X - 2y = - 9
7x + 2y = 1
x - 2y = - 9
(+)
7x + 2y = 1
___________
8x = - 8
x = - 1
- 1 - 2y = - 9
2y = 8
y = 4
